A better way to go with cast big ends in the 216 & 235 splash feed engines is to have the rods bored to take shell type bearings which can be purchased in standard or a range of undersizes from US suppliers such as Jim Carter Antique Truck Parts. These shells are made specifically to suit this application. You also have to file a notch for the anti-rotation nib. 
Main bearing sets are also available in a range of finished sizes.
